4-(1H-imidazol-1-ylcarbonyl)-3,5-dimethyl-1H-pyrrole-2-carbaldehyde (6.8 g, 31.3 mmol), (2S)-1-amino-3-morpholin-4-ylpropan-2-ol (10.0 g, 62.5 mmol), 5-chlorooxindole (5.3 g, 31.6 mmol), and THF (100 ml) were mixed and heated to 60° C. After stirring for 68 h at 60° C., triethylamine (14 ml) was added and stirred for 5 h at 60° C. Added 4.6 g of (2S)-1-amino-3-morpholin-4-ylpropan-2-ol, and stirred for 20 h at 60° C. The yellow slurry was cooled to room temperature and filtered. The cake was washed with 2×50 ml THF and dried overnight at 50° C. under house vacuum. 5-[(Z)-(5-chloro-2-oxo-1,2-dihydro-3H-indol-3-ylidene)methyl]-N-[(2S)-2-hydroxy-3-morpholin-4-ylpropyl]-2,4-dimethyl-1H-pyrrole-3-carboxamide (5.48 g) was obtained with 38% yield.
